- Letters Patent No.1113,242, dated April 4, 1871.

IMPROVEMENT IN FLUTlNG-IVIACHINES.

The Schedule referred to in these Letters Patent making part of thesame.

I, S. WILLIAB( BABBlTT, of West Meriden, in the county of New Haven andState of Connecticut, have invented certain Improvements VinIiluting-IMIachines,l

'of'. which the following is a speciiication.

Nature uml Objects of the I iwentiou.

My machine is designed for luting or crimping cloth, and. consists oftwo metal rolls fitting and turning together very much as twogear-wheels turn together.

These rolls are removable from their axes and the axes are supported atone end only.

My machine is designed mainly for household usc, and is made with ascrew-clamp for the purpose of securing it to a table. Allilutiug-inacliines use heated rolls, and the heating is usually effectedby having one or both the rolls hollow, for the purpose of introducing'therein from time to time bars of hot iron.

My improvements consist- First, in making the rolls detachable fromtheir axes,

so that they may themselves be heated.

Second, in having the axes of the rolls supported from one end only,thus leaving the rolls fully open at the other end. l

Third, in a novel adjustment for separating the rolls when desired.

Fourth, in attaching a clamp to the machine so that it can be readilyfastened to the table.

Description of the Accompanying Drawing.

Figure 1 is a side elevation.

AFigure 2 is an end elevation of the end, upon which is the crank. fFigure 3 is a central vertical section of the main upright, showing theconstruction of iny peculiar adjustment for separating the rolls whendesired.

General Description.

The letter a indicates the metal frame of the machine, and

b, the screwclamp for securing it toa table.

The lettere indicates the' shaft of the lower roll, bearing thehand-crank (Z.

The lower roll eisfast to its shaft The upper roll f is loose upon itsshaft, and is driven by the lower roll. p

Duplicates of the loose upper roll are necessary, so that while one isin use the other is being heated.

As the roll fis loose upon its axis it is readily slipped off andreplaced by its duplicate when desired; or, if preferred, the roll f canbe secured upon its shaft by a wire pin, y.

The axis h of the upper roll is square at one end, just sliding in aslot, i., in the upright a', and it is fast'- ened on the rod la whichruns through it.

This rod L slides up and down in the bearing m which caps the uprighta', and also in the bearing n below the slot e'.

A spiral compression-spring, o, bearing against the cap m on one sideand against the square head of the axisor shaft h on the other, forcesthe upper-'roll down upon the lower with the necessary force.

The rod k is jointed at the top to the cam s, which has a handle, s',and when this handle is thrown down into the position shown by thedotted lines in fig. 2, the upper roll will be raised to the positionshown by the dotted lines in g. 2, when the cloth can he introducedbetween them or the rolls changed, a cold one taken off and a hot oneput on. A

I do not claim, broadly, rolls supported only at one end, nor theadjustment of a movablel roll with relation to a fixed one by means of acam-lever and other devices; but

I claim as my invention- A liuting-machine, composed of the hollowremovable roll f mounted loosely on shaft It, having a vertical movementin the slot e' of the upright a', the rod k, spring-o, and cam-lever ss, the roll e. shaft o, and crank d, and the frame a a a' provided withthe screw-clamp b, all constructed, arranged, and operatiu gsubstantially as herein described.
